For me it has to be the tracking everything I eat, I have done this since I started the ww diet, I always try and drink lots of water, and make zero pointed soup when I am hungry, and I make sure I eat at least 3 hours before I go to bed, I always allow myself a treat everyday, I try to vary my diet as much as possible, I have done this for 6 and a half months and I have always lost weight.
